To 60% whom it may concern.-

Be it known that we, CHARLES ALBERT MILLER and FREDERICK J OHN MILLER, managing directors of 1V. Miller A: Company, Limited, subjects of the Queen of Great Britain, residing at Miller Street, in the city of Birmingham,England,have in vented certain new and useful Improvements in OycleLamps, of which the following is a specification, and for which Letters Patent of Great Britain have been obtained dated, respectively, the 19th day of September, 1896, and numbered, respectively, 20,740 and 20,711.

This invention relates to lamps principally adapted for burning light volatile oils, such as paraffin, and employed on cycles, motorcarriages, and other road-vehicles, and has for one of its objects a smokeless lamp not liable to be extinguished by ordinary vibration, for another object screening the reflector and other bright interior parts of the lamp from the products of combustion of the flame, and for a further object a new construction of lamp whose component parts admit of being easily assembled.

Fig. 23 is an under side plan of the foot of the lamp-body,

Fig. 26 is a like View of the lower bracketplate blank. .Fig. 28 is a detail view illustrating the means employed for connecting the inner and outer rings h if.

The same letters of reference indicate corresponding parts in the several figures of the drawings.

The lamp consists of a shell-body part or light-chamber a, having a foot a upon its under side supported from the top Z) of the gallery I), wherethrough the hollow and cir- 8o cular wick-tube c or casing and central air shaft 0 up its middle axially pass, with their upper ends 0 0 extending into the mouth or circular opening (1 of the cone or burner (Z,

located within and made a stationary part of 8 5 the body or light-chamber, which is formed from a spherical shell having parts or sections a a a a a removed to form openings 6 f g Ib a for the hinged bell or front light 6, the reflector f, the side lights g, the crown or head It, and foot a of the lamp to fit Within. Thus the body, which is made from a spherical shell, has at its inside bottom a burnercone (1, with a circular burner-hole cl through its middle coming coincident with the wick and with the walls stepped or shouldered at d to receive and form the rest for a glass chimney 2, which extends upwardly through the middle of the body and terminates in an upper and inner ring 71, having inside spring IOO holders or bearings 71. and being carried. by an outer and separated ring 7L3, made fast to the top a of the shell-body, connected to the inner ring 7t by bridging-webs 71 A space .or passagej is left between these rings open to the atmosphere to admit of cooling-currents passing through the body of the lamp and of the removal therefrom of all moisture, which in ordinary lamps dulls the glazings and polished surfaces, and which currents may be utilized also to promote the combustion of the burner-flame.

Fitted upon the aforesaid inner ring is a loose sleeve or guard-ring 7a, with its lower edge 70 overhanging and standing away from the outer ring, being separated therefrom by an annular space 7& wherethrough air-currents may pass into the interior of the lamp or ascending currents may pass outwardly for ridding the interior of moisture and while the upper edge k rests upon a shouldered or stepped and screwed part 70 of the inner ring,

which also receives the head or external chimney h, consisting of a conical-shaped neck 77.5 open at top 72/6 and bottom 71 with the latter fitting and screwing upon the aforesaid screwed part of the inner ring. Closed to the top of the neck is a breaker h and above the breaker comes the cowl 7L9, separated from the said breaker by a space 773, wherethrough the products of combustion from the internal glass chimney-outwardly pass.

By employing a head screwing upon the sleeve surmounting the body of the lamp the said head is made detachable and the internal chimney can be readily withdrawn from the lamp for cleaning.

The front opening 6' in the body of the lamp, whose boundary edge e is wire-beaded, has an independent cone 6 of the figure of a bell gapped at its inside top and bottom edges at e e to clear the internal glass chimney 2' and the burner-cone d, while fitted to and hinging upon the same joint 6 is a bezel e for carrying a lens 6 or other glazing, both cone and bezel opening independently, socketing into the beaded front opening and being fastened in common by the same catch 2 The front a of the foot of the lamp is extended and hinged to a like extended part or annular plate 5 carried on the gallery, while the opening f in the back of the body, whose edge f is wire-beaded, is closed by a hinged reflector f, consisting of a hollow and pierced back f and edges f with a set or shoulder f formed thereon for the reception of' the edges of the silvered glass or other reflector f affixed in .position by turning the said edges f of the hollow or box back, through which air-currents may pass over the edges f of the reflector.

The side lights g consist of glazed rings g with necks passed through the openings g in the body sides and closed over the edges of the same. A

The gallery 6 consists of an inverted-hatshaped shell pierced at its lower edges or at front and affixed to the lower part of the wick tube or casing c by the lower end 0 of the said tube having a screwed pom1nelc and an upper shoulder 0 up to which the pierced bottom 19 of the gallery comes and is there affixed by a closing operation which at the same time secures a bracket-plate m, with a rearwardly-extending and lower back-strap arm m, in position. The upper back-strap arm m is formed from a back extension of the flange b at the top edge of the gallery, while coming between the sleeved ends m m of the said strap-arms is a back-strap m formed alike in shape to achair-bracket fashioned fromthe blank of sheet metal and turned staplewise upon itself and through gaps m m, in which the releasing-arm n and catch end n of a fastener n for fixing the body to the gallery pass, while the stand side part a of the spring rests upon and is secured to the inside back of the strap. The combined oil-tank and base 0 screws upon the screwed pommel c at the bottom of the gallery.

The body of the lamp is connected to its foot or rest a by obliquely cutting its bottom opening a at a slight angle, so as to cause the rays of the light to be directed slightly obliquely downward instead of horizontally.

The wick casing c is surrounded by a pierced baffle-tube p, fitted with an ordinary winder p, and is circular at top, gradually opening out to a section comprehending twothirds of a circle at the bottom,thereby gradually converting a flat wick into a circular one.

It is understood that when the body of the lamp is turned or thrown forward on its gallery for gaining access to the wick for lighting and trimming the burner-cone and the whole of the cognate parts of the lamp above the burner are carried forward with it.

The head or external chimney may be made from three blanks of sheet metal, the neck 72/ being formed by a cupping process, with the middle of the bottom out out and the other parts connected to it by closing the edges over one another. The crown is made from a hatshaped blank 77. while the sleeve, rings, and otherv junction parts of the head and body may be made by drawing and spinning processes. (See Fig. 7.)

The body or light-chamber is fashioned fromv a die-formed or spun sphere of thin sheet metal, from which top, bottom, back, front, and side segments are removed to form openings for the bell, reflector, side lights, head and foot or base,as previously described. (See particularly Figs. 17, 18, and 19.)

The foot a is made from a circular stamping, with a neck a at the middle, (see Fig. 8,) which is passed through the hole a in the foot of the body-shell and then clenched or closed.

The gallery Z) is formed from a cup-shaped stamping (see Fig. 8) with a flanged mouth.

The wick-tube and air-shaft c 0 may be made by part stamping and part drawingthrough processes and be put together without soldering by closing.

The oil-tank o is built up from two cupped stampings o 0 (see Fig. 14,) with their meeting edges 0 closed over each other, or it may be made from a single blank by a rolling process or by spinning.

The wires q of the headings q, surroundin g. the openings of the shell, which when pierced constitutes, as it were, a cage for the burner, form joints for the closure parts to turn upon. (See Figs. 10 and 12.)

The lamp described can be adapted for burning heavy oils, as well as paraffin and like light oils. v

Having fully described our invention, what we desire to claim and secure by Letters Patent is 1. In cycle and road-vehicle lamps, the co1nbination with the lamp-body a provided with the burner-cone (Z and chimney i, of the gallery b, and the foot a attached to the under side of the lamp-body and hinged to the gallery, substantially as described.
